Is there a way to bind to properties on a parent control from a itemcontrols template?
For example, I have the following template for a ToggleButton which is then used in a Template for a ComboBox:
<ControlTemplate x:Key="DefaultComboBoxToggleButtonTemplate" TargetType="{x:Type ToggleButton}"><Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(GradientBrush.GradientStops)[1].(GradientStop.Color)" Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0"Value="{Binding Path='property on local:ComboBox', RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type local:ComboBox}}}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed" />
<VisualState x:Name="Disabled">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(GradientBrush.GradientStops)[1].(GradientStop.Color)" Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource DisabledControlDarkColor}" />
</ColorAnimationUsingKeyFrames>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="Arrow">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource DisabledForegroundColor}" />
</ColorAnimationUsingKeyFrames>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Border.BorderBrush).(GradientBrush.GradientStops)[1].(GradientStop.Color)" Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource DisabledBorderDarkColor}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="CheckStates">
<VisualState x:Name="Checked">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(GradientBrush.GradientStops)[1].(GradientStop.Color)" Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0"Value="{Binding Path='property on local:ComboBox', RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:ComboBox}}}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Unchecked" />
<VisualState x:Name="Indeterminate" />
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
<Border x:Name="Border" Grid.ColumnSpan="2" CornerRadius="2" BorderThickness="1">
<Border.BorderBrush>
<LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="{DynamicResource BorderLightColor}" Offset="0" />
<GradientStop Color="{DynamicResource BorderDarkColor}" Offset="1" />
</LinearGradientBrush>
</Border.BorderBrush>
<Border.Background>
<LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
<LinearGradientBrush.GradientStops>
<GradientStopCollection>
<GradientStop Color="Transparent" />
<GradientStop Color="Transparent" Offset="1.0" />
</GradientStopCollection>
</LinearGradientBrush.GradientStops>
</LinearGradientBrush>
</Border.Background>
</Border>
<Path
x:Name="Arrow"
Grid.Column="1"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Data="M 0 0 L 4 4 L 8 0 Z"
Fill="{TemplateBinding Foreground}"/>
</Grid>
</Border>
</ControlTemplate> The bold italic part does not work, but you should see what I want to do.
